Nihonbashi Idumoya
3 minutes from Shin-Nihonbashi Station. Founded in 1946, this Nihonbashi landmark has served authentic Edo-style eel for over 75 years. Authentic unagi from 2,420 yen (unadon) to 3,520 yen (unaju regular) — genuinely affordable. Selected for Tabelog Unagi 100 in 2024. TripAdvisor 4.5. Office workers from surrounding buildings line up at lunch. Two buildings (main and annex), with the main building being the original.
Long-time regulars say: 'The traditional taste unchanged since 1946', 'A 3,520-yen unaju of this quality is a hidden sanctuary for office workers', 'The depth of the sauce and fluffy eel is outstanding'. Tabelog 3.67/425 reviews, TripAdvisor 4.5, Tabelog Unagi 100 2024.
